Poor design costs money in terms of maintenance and enhancement lead times. Not only does poor design consume resources but it also leaves you with dissatisfied and confused customers.

Software engineering has traditionally been associated with process models that say very little about how you go about building quality into your design. This has changed recently with the advent of agile approaches such as eXtreme Programming (XP) that focus on the concepts, principles, patterns and techniques that underpin quality designs.

How do experienced OO developers cope with the complexity inherent in software design? They do the simplest thing possible to solve a problem, plus …

- Apply design patterns where appropriate.

- Continuously look for weak spots in the design in order to refactor them out.

- Say “what”, before they say “how”, i.e. Write tests before they write solutions.

This course will teach you how to design high quality OO solutions using Test Driven Development (TDD), refactoring and patterns.

The course is lab based, with every new concept backed up by a comprehensive set of exercises that allow you to validate your understanding of the material. Participants will work in pairs.

A detailed syllabus is available for this course.

This course is part of our Design Service roadmap.

At the end of this course you will be able to:

• Use patterns, refactoring and unit testing to produce high quality OO designs.
• Capture and manage user requirements in the form of acceptance tests.
• Use the testing tools, JUnit and FIT.
• Know how to effectively use UML to quickly drive a “first cut” design.
• Act as a design mentor.
